Gongshuilong

Gongshuilong's tail bones were super long, making the tail look like a sail. The neural spines were 8.5 times as tall as the bones they attached to, which is unique among all iguanodontian dinosaurs.1

It was a medium-sized hadrosaur, about 7 metres (23 feet) long, which is about as long as a small school bus.1

Gongshuilong is the second brachylophosaurin found in Asia, after Wulagasaurus. Most of its close relatives lived in North America, so it helps show that this group might have started in Asia.1

The fossils were found in a bonebed with at least two individuals, because scientists found two left lower jaws, two shoulder blades, and two shin bones of different sizes.1

Its name, Gongshuilong, comes from the Gong River near where it was found, and 'long' means dragon in Chinese.1

The species name 'fanwei' refers to the sail-like tail, because 'fan' means sail in Chinese.1
